Followup to https://github.com/astropy/astropy-helpers/pull/43 -- the output from automodapi includes the :functions-only: option to automodsumm.  The test previously did not include this, and so some code paths that checked inspect.isfunction were not followed.  I went ahead and updated the test to include this additional constraint (which covers the simpler use cases as well) and changed all uses of isfunction to isroutine which is fine in this context.
